GM's 4bbl carb intake for LT1's
Has anyone here, or known of, ever switched over to this carbed intake manifold set up that GM offers for the LT1 ?
Probably would require a lot of modifying to the stock system right? (aside from the obvious)
But, in a way, it might be :cool:
Obviously not for your average 'street' set-up.

It allows you to use a carb and a standard distrbutor on your LT1. Essentially it would let you retain the benefits of reverse flow cooling without having to make the electronics work. It seems like something you would want to use in a street rod or anything else you didn't want to have to make computer controlled.
I don't think you can put it on a C4 with the stock hood.

I dont really know much about the LT1/4's as far as swaps go or them being remotly the same size intake, but I have seen an LT4 with the GM carb intake on it like that set up for EFI.
He used a C5 throttle body. He also had a tube made to fit under the hood and welded into a carb plate.
The dist hole was convereted over to a breather but it was puking oil on the autoX track. I think some sort of baffle would of solved that.
This car also had an electromotive tech 2 system on it, which gets rid of the Opti and replaces the computer.
I rode in it, and it pulled really hard, only other big mod on it were headers and exhuast. the internals of the engine were all stock.

I didnt know there was a benefit to reverse flow cooling, didnt they switch back to the old style with block being cooled first?

the advantage to reverse flow cooling is simple - reducing the expansion rates of the 2 divergent metals.
Aluminum and iron expand at different rates... the reverse cooling will not eliminate it, but will lower it.
